Effect of drying technique on the physicochemical properties of sodium silicate-based mesoporous precipitated silica

► This paper reports a highly porous silica powders by drying the precipitated wet-gel silica slurry using spray drying technique. ► The spray drying technique effectively removed the water from the wet-gel silica slurry. ► Spray drying is proposed as the best drying technique for the large-scale industrial mass production of highly porous silica powders.
